I honestly think this is one of the best VST chorus plugins, free or otherwise. The controls are simple, but there's still a lot of versatility - can go from subtle stereo widening to full on lush chorus.
There is one thing that is not small, and fortunately that is the sound. This is one of those plugins that you throw on a mediocre track, say a simple synth pad, and it immediately comes to life. And then you turn it off again, but not for long.
But let's not get carried away and stay with the facts. The TAL-Chorus-LX is modeled after the on board chorus of the Juno-60. It is very easy to use as it has just two buttons for two different chorus modes which can be switched on separately or used together. Mode II is more intense than mode I, and if you want the full monty, you'd go for both combined.
Then there are three knobs for setting the volume, the effect mix level and the stereo with. This reduced control set makes the plugin so simple to use that even the most die-hard analogue stomp-box guitarist can handle it (and they should, as it works just as well on guitars as on synthesizers!). You don't have to step through long preset lists or twiddle many knobs, it just takes a moment to select the mode, dial in the correct amount and you are rewarded with a wonderful, lush and mellow chorus sound.
The ease of use combined with the sound and the fact that it's free makes this a perfect plugin.
